Comment by Najla Bulous (JIRA)

This is a Swift toolchain regression that seems to be simulator architecture specific and causes Xcode to crash. I can reproduce it with the iPhone 4s, iPad Retina, iPad 2, and iPhone 5 simulators with the following steps:

Xcode: 7C68
OS: OS X El Capitan 10.11.2
Toolchain: Any

1. Launch Xcode with toolchain
2. Create an iOS app and set a break point in AppDelegate.swift
3. Select either the iPhone 4s, iPad Retina, iPad 2, or iPhone 5 simulator
4. Run the app
--> Crash

Has this been resolved and is it no longer relevant? If either, it should be closed.

closing this since I do not have an environment that can be reproduced anymore.
